Characteristics of elastomers-friction damper [PDF]
AIP Conference Proceedings, 2018 The effect of the work of currently designed vibration dampers is the implication of the structural solution and the materials used for the cooperating elements. A desirable solution in the construction of machines would be a silencer with a constant, temperature-independent level of energy dissipation. An evaluation of the work of silencers preventing

Study on damping characteristics of steam turbine hollow vane with damper
Nihon Kikai Gakkai ronbunshu, 2014 A vane used in a low pressure end of steam turbine is usually fixed to a shroud and a casing by welding both ends. In such a vane structure, the damping in loading operation is comprised of the material damping and the aerodynamic damping, because the ...

Prototype Test of Resilient Friction Materials for Seismic Dampers
Materials, 2023 In recent decades, low-yielding seismic devices based on the use of friction dampers have emerged as an excellent solution for the development of building structures with improved reparability and resilience. Achieving an optimal design for such low-yielding seismic devices requires precise control of bolt preloading levels and predictability of the ...

A Semi‐active piezoelectric friction damper
Earthquake Engineering & Structural Dynamics, 2014 SummaryThis research investigates the development of a semi‐active piezoelectric friction damper for controlling the seismic response of large‐scale structures. The proposed device is made of Duplex steel and leads to high friction capacity, which can be developed either in passive or semi‐active modes.
